Here is another short (IMHO) example how to post in android app.
[java]
private void postSms(String text) {
URL url;
HttpURLConnection urlConnection = null;
try {
url = new URL(“http://yourserver.com/sendsms”);
urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod(“POST”);
urlConnection.setDoOutput(true);
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair(“sms”, text));//POST param as “sms”
OutputStream os = urlConnection.getOutputStream();
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(os, “UTF-8”));
writer.write(getQuery(params));
writer.flush();
writer.close();
os.close();
String status = new String(Streams.getBytes(urlConnection.getInputStream()));
Log.d(TAG, new Exception().getStackTrace()[0].getMethodName() + “:insert status=” + status);
} catch (MalformedURLException | ProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
[/java]
This is a method for concatenating parameters for POST
